I deleted both, downloaded the 0.1.8 once again, tried installing it: still told me there was a conflit with an existing package...
After writing my comment, I actually found another file I had downloaded of the last version.
I deleted it and downloaded the last update, and it all works properly now, thanks :)
The only (kinda) downside is that I have to go through the whole game again. Which is not that bad.
Yeah, i may end up having to do the same thing, i really wanna continue my progress, but i also just want to continue the game as well.
